To all whomit may concern:

Be it known that 1, CHARLES CAMMACK, a citizen of the United States,residing at Crossett, in the county of Ashley and State of Arkansas,have invented; certain new and useful Improvements in Silo-Doors, ofwhich the following is a specification, reference being had to theaccompanying drawings. 1

This invention relates to certain improvements in silo doors, and anobject of the invention is to provide a novel and improved (lGTlCG ofthis general character whereby the door may be applied into operativeposition with convenience and facility and whereby the door, after beingso applied, may be effectively maintained in operative position.

The invention also has for an object to provide a device of this generalcharacter including a novel and improved hinge for a silo ClOOr wherebythe door may be easily and readily swung outwardly throu h the dooropening so that access may be ad to the interior of the silo.

The invention consists in'the details of construction and in thecombination and arrangement of the several parts of my improved silodoor, whereby certain important advantages are attained and the deviceis rendered simpler, less expensiveand otherwise more convenient'andadvantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in theappended claim.

In order that my invention may be the better understood, 1 will nowproceed to de scribe the same with reference to the accompanyingdrawings, wherein- Figure 1 is a fragmentary view in elevation of asilo, illustrating a door secured thereto in accordance with anembodiment of my invention; Fig. 2 is a sectional view Specification ofLetters Patent.

the jambs secured along the edges of the door-way 2.

As each door is substantially identical in construction, it is thoughtthat a description of one together with its concomitant parts will.sufiice for the purpose of disclosure. 5

4 denotes a door adapted to be inserted through the door-way 2 and tooverlie the ]ambs 3, in a manner which is believed to be self-evident,and the outer faces of the door are provided with the longitudinallydisposed parallel bars 6, theintermediate bar being disposed atsubstantially the transverse center of the door.

Secured to one of the jambs 3 substantially midway of a door-way oropening is a bracket 7 provided with the outstanding spaced arms 8provided with alined openlngs 9 through which is adapted to be directeda pintle 10, said pintle being also adapted to be directed through thebarrel or sleeve 11 formed at one extremity of the hinge member 12.

As herein embodied, the portion of the hinge 12 immediately adjacent thebarrel or sleeve 11 is disposed on a segment of predetermined radius,while the opposite extrem ity thereof is elongated and terminates in abarrel or sleeve 12 adapted to be received between the arms 14 of thebracket 15 securedgto the intermediate bar 6, said arms being providedwith alined openings 16 through which is adapted to be directed thepintle 17, said pintle 17 being also adapted to be directed through thesleeve or barrel 12. By this arrangement, it will be readily perceivedthat the door 4 is conveniently and eii'ectively maintained in hingedposition relative to the silo 1, and said hinge is of a portable type,whereby the same may be applied with convenience and facility at thetime required. In order to maintain the door effectively in closedposition, I employ the elongated member 18 having one end 19 angularlydisposed and pivotally engaged with a jamb 3 through the medium of ahorizontal pivot, as indicated at 20, whereby said member may be swungupwardly, and the opposite end portion of such memher is adapted to bereceived within the catch 21 carried by the opposite jamb 3 with theintermediate portion of saidelongated member resting upon the upper arm14, the free extremity of such arm being upturned, as indicated at 22,whereby it will be perceived that the door 4 will be effectivelymaintained in closed position. It will also be observed that the member18 serves as a step or bar adapted to coact with the immovable members22 positioned above and below the door opening 2 to afford a ladderconstruction, for a purpose which is believed to be. self-evident.

From the foregoing description, it is thought to be obvious that a silodoor constructed in accordance with my invention is of an extremelysimple and comparatively inexpensive nature and isparticularly welladapted for'use by reason of the convenience and facility with which itmay be assembled, and it will also be obvious that my invention issusceptible of some change and modification without material departurefrom the principles and spirit thereof and for this reason I do not wishto be understood as limiting myself to the precise arrangement andformation of the several parts herein shown in carrying out my inventionin practice.

1 claim:

The combination with a silo having a door-way and a door seatableagainst the inner side of the silo, of a bracket secured to the door atsubstantially the center of the outer face thereof, said bracketcomprising vertically alined arms, the uppermost of said arms beingupturned, a hinge member for the door detachably engaged between theears of the bracket, and a locking member for the door disposed acrossthe doorway and coacting with the upturned portion of the upper arm ofthe bracket.

In testimony whereof I hereunto aflix my signature in the presence oftwo Witnesses. CHARLES CAMMACK. vWitnesses:
